2 Claims.

This invention relates to a combination bumper guard and jack for abumper bar of an automotive vehicle.

An object of this invention is to provide a jack which is adapted to bereadily assembled with the bumper bar of any automobile to serve as abumper guard.

Another object of this invention is to provide a jack adapted to befirmly mounted on the bumper bar of an automobile, the jack forming aprotective bumper guard which is decorative and ornamental.

A further object of this invention is to provide a combination bumperguard and jack which is light in weight, relatively simple inconstruction and cheap to manufacture.

The above and still further objects and advantages of the invention willbecome apparent upon consideration of the following detailed descriptionof the invention, when taken in conjunction with the accompanyingdrawings, wherein:

Figure l is a front elevational view of the combination bumper guard andjack of the present invention, shown mounted on the bumper bar of anautomotive vehicle;

Figure 2 is a sectional view taken along the line 2-2 of Figure 1;

Figure 3 is a sectional view taken along the line 3-3 of Figure 1;

Figure 4 is a sectional view taken along the line 6-4 of Figure 1;

Figure 5 is a perspective view of a locking device forming a part of thejack of the present invention; and

Figure 6 is a perspective view of an adapter plate forming a part of thecombination bumper guard and jack of the present invention Referring nowmore particularly to the drawings, wherein like reference numerals havebeen used throughout the several views to designate like parts, there isshown the combination bumper guard and jack of the present invention,generally designated by the reference numeral l0, shown secured to thebumper bar of an automotive vehicle. Y

The combination bumper guard and jack l0 embodies a hollow bumper guard|2 adapted to engage the outer surface of the bumper bar The bumperguard I2 is provided with a chrome finish and includes opposed lateralextensions I3 and I which abut against the adjacent face of the bumperbar Abuttingagainst an opposed portion of the inner face of the bumperbar I! is an adapter plate l5, Figure 6, which has one face l3 shapedcomplementary to the adjacent face of the bumper bar Abutting againstthe other face of the adapter plate I5, which is plane, is a jackhousing or jack screw housing :|1 which includes lateral opposedextensions 13 and I9.

As clearly shown in Figure 3, bolts extend transversely through theassembly of the outer bumper guard l2, the bumper bar the adapter plate[5, and the jack housing l1, for detachably securing the assembly to thebumper bar H, the bolts being designated by the reference numerals 2Band 2|.

Extending transversely through aligned apertures 22, 23 provided in thebumper bar II and the adapter plate I5 is a shaft 24 which has one endprojecting into said bumper guard and adapt ed to be engaged by a crankhandle 25, and has the other end projecting into the jack housing orjack screw housing H. The shaft 24 extends through an opening in thebumper bar and is rotatably journaled intermediate its ends in theadapter plate I5, the end projecting into the jack housing or jack screwhousing being journaled therein, as indicated by the reference numeral25.

As clearly shown in Figure 2, the face of the jack housing or jack screwhousing I! contiguous to the adapter plate I5 is provided with alongitudinally extending slot 21 which has its lower end incommunication with a transversely extending slot 28' provided in thejack housing. Positioned within the longitudinally extending slot 2! andsecured to the adjacent projecting end of the shaft 24 is a beveled gear28. The jack housing or jack screw housing I! is further provided with alongitudinally extending bore 30 accommodating a longitudinally slidablejack shaft or jack screw 3| which is provided with a screwthread 32.Rotatably supported within the transversely extending slot 28 is abeveled pinion 33 which is in meshing engagement with the gear 28 and isprovided with an internally threaded bore receiving the jack shaft 3 Theupper face of the beveled pinion 33 bears against the adjacent boundingwall of the slot 28, and, upon being rotated by the gear 28, will causethe jack housing IT to climb the shaft 3|. The lower end of thejackshaft 3| is rounded, as indicated by the reference numeral 35, andis embracingly received and supported within the jack base 36. The jackbase 36 is circular and has a diameter large enough to support thejackshaft 3| with the desired stability. It is readily apparent that thedisassembly of the jackshaft 3| and the supporting base 36 can beeffected by merely moving the lower arcuate end out of its supportedposition.

Circumposed about the upper end of the jack shaft 3| is an auxiliarybumper guard, generally designated by the reference numeral 3''! whichslidably receives the jackshaft and is supported on the jack housing IT.The auxiliary bumper guard embodies a tube 38 which is provided with alongitudinally extending slot 33, the slot receiving a pin 49 extendingtransversely of and secured to the adjacent end of the jackshaft 3|. Thejaekshaft 5| also carries a spring biased ball 4| which is engageablewith an opposed por tion of the tube 38. It is to be noted that thespring-biased ball 41 prevents a rattle from developing between theupper end of the jackshaft 3i and the pipe 55 circumposed thereabout.The pin 40 cooperates with the longitudinally extending slot 39 tosupport the jackshaft for sliding non-rotative movement with respect tothe auxiliary bumper guard 31. about the tube 33 is a chromium sleeve 42which forms a decorative covering for the bumper guard 31 and bridgesthe slot 39 to thereby form a dust-proof chamber for the reception ofthe upper end of the jackshaft 3!. The dust-proof chamber is completedby a decorative closure cap 43 which is supported on the upper open endsof the tube 38 and the chromium sleeve 42.

Carried interiorly of the bumper guard 12 is a locking device, generallydesignated by the reference numeral 50, Figure 5, which is normally incontacting engagement with the adjacent end of the shaft 24 andrestrains the latter against rotation. As clearly illustrated in Figure5, the adjacent end of the shaft 24 is squared, as illustrated by thereference numeral 5|, and ha its free end adapted for support within thesocket 52 of the crank handle 25. The locking device embodies a plate 5|which is provided with apertures 52' for the extension therethrough ofsecuring elements to thereby secure the plate 51 in abutting engagementwith respect to the adjacent exterior face of the bumper bar H.

Fixedly secured to the upper end of the plate 5| is a resilient arm 53which has its free end 54 turned downwardly and inwardly, as shown. Aslot 55 extends inwardly from a point contiguous to the free end of thearm 53 and terminates at a point substantially midway between the endsof the arm 53. The side bounding walls 56, 5'! of the slot 55 normallybear against the adjacent faces of the squared end 5| of the shaft 24 tonormally restrain the latter against rotation. It is to be noted thatthe locking device 50 also supplies the constant pressure to the shaftto prevent the latter from rattling within the assembly of the bumperguard I2, the adapter plate and the jack hOusing 17. Upon inserting thesocket 52 of the crank handle into the aperture 58 provided in the outerbumper guard 12, the end face of the socket will bear against theadjacent portion of the resilient arm 53, to thereby urge the side edges58, 5'! of the slot 55 out of their position of engagement with thecrankshsaft 24 to thereby permit the free rotation of the latter. It isto be further noted that the resilient arm will bear against the socket52 when the latter is supported on the crankshaft 2:1 to therebyeffectively restrain the crank handle 25 against removal from itssupported position.

In actual use, the securement of the outer bumper guard [2, the adapterplate l5 and the jack housing I! to the bumper II is effected by meansof the bolts 29 and 2|. Upon inserting the socket 52 of the crank handle25 into the aperture 53 provided in the outer bumper guard [2, thelocking device is brought out of its contacting position with thecrankshaft 24 to thereby permit rotation of the latter by the crankhandle. Upon imparting a counterclockwise rotation to the crank handle,a clockwise rotation will be imparted to the beveled jack gear 33 tothereby urge the latter upwardly along the jack- Circumposed' shaft 3|,the upward movement causing a corresponding upward movement of theassembly of the bumper II and the outer bumper guard I2, the adapterplate [5 and the jack housing 11. Accordingly, the position of thebumper H can be effectively varied within the limits predetermined bythe length of the jackshaft 3|. It is to be noted that the jackshaft 3|is non-rotatably held within the auxiliary bumper guard 31, andggcordingly will not turn on the supporting base Although only oneembodiment of the combination bumper guard and jack of the presentinvention has been described, it is readily apparent that numerousmodifications can be made without departing from the spirit of theinvention as set forth in the appended claims.
